In ancient times, evil cultivators broke the seal and caused trouble in the three realms. Immortals, spirits, and demons each acted as barriers, and the war started.
Mo Yuan, the god of war in the fairy world, wields his sword to quell the chaos. He meets Bai Li, the goddess of the spiritual world - she restores his remnant soul with her healing power, and he protects her with the Kunlun magic. From testing each other to trusting each other in life and death, the red threads are crossed and feelings are secretly born. The young master of the Demon Realm, Yan Xie, wanted to seize the secret treasure of the spirit world, but he ran into Lingxi, the grass elf. She bound his edge with vines, and he warmed her loneliness with fireworks. The two people with opposing views finally untied their knots when they fought side by side against the enemy.
When the evil cultivator performs a world-destroying killing move, the four of them put aside the barriers between the realms and use fairy power, healing, demon fire, and vegetation to weave a protective net to finally destroy the evil cultivator and establish a covenant in the three realms.
The Immortal Lord returns to the ruins to plant flowers with the Goddess, and the Demon Lord Yin Zhu and the Elf grow grass. The two pairs are a match made in heaven. In the peace of the three realms, they spend time together with fireworks every year.
